A very RAW guide of my notes to get up to speed with understanding version 8. It is not an article so forgive me if it jumps a bit. It is part one of a three part series I am creating this week.
I choose to install on CentOS 6.3 for this demo
Yum install firefox, then run ./launchpad. all is good
Use this page to configure this server or cluster as a Process Center, which primarily serves as a Process Application repository, providing a test environment for all Process Designer users and allowing Process center users to manage registered Process Servers.
In your development environment, the Process Center server enables you to run processes as you build them. When you’re ready, you can install and run those same processes on the Process Servers in your test and production environments.
Note: You can configure a server/cluster as either a Process Server or a Process Center but not both.
To view this page in the administrative console, do the following:
If you are configuring a server:
Click Servers > Server Types > WebSphere application servers > server_name > Process Center.
If you are configuring a cluster:
Click Servers > Clusters > WebSphere application server clusters > cluster_name > Process Center.
The Process Center component requires a service integration bus to provide messaging services. You need to select a server or cluster to provide these services.
You can select this server or cluster (sometimes referred to as a Local target configuration) or another server or cluster (sometimes referred to as a Remote target configuration) to provide the messaging services.
You create the database configuration for the Process Center by importing a database design document.
Select this check box to enable the Process Center configuration parameters on this page.
By default, this check box is cleared.
If you are using a stand-alone server profile, or have previously configured Process Center support, the Enable Process Center check box is selected and the panel is read-only (configuration parameters can be viewed, but can not be changed).
When you select Enable Process Center, each section of the panel becomes active so you can specify configuration settings and perform configuration operations.
Use this portion of the panel to import a database design document that defines the database metadata definitions for the Process Center and its Performance Data Warehouse.
Note: The Process Center database design file might contain information about other components (not related to Process Center). Only information for the Process Center component will be used. No other database configuration will be updated.
Select Browse to locate the database design document on your system or enter the path to the file in the text field.
Specifies the location / destination of the Process Center Bus. The destinations can be the local deployment target or on a remote target. Use the On this deployment target and On a remote deployment target radio buttons in this panel to indicate the appropriate location.
Bus members are always hosted locally for stand-alone server profiles.
Select this radio button if the Bus Member will be configured on this server or cluster.
Select this radio button if the Bus Member will be configured on another server or cluster (not the server or cluster you are currently configuring).
If you select On a remote deployment target, use the associated drop-down list to specify the remote location you want to use. The drop-down list shows all deployment targets.
Launch pad issues
When clicking on install buttons it does nothing. Man alive, no wonder we neeed certified platforms!

|Re start launch pad and try again. This was me be lazy and not reading he Red Hat pre-requisites|
We are now installing IIM and the sofware ie process server. Accept license and click Next
Leaving default, since I don’t care on the VM ands want to see what happens with default installation paths. Then I do not need to worry about wrong paths in IBM help docs.
I am not creating profiles; we can sort that out later
I Set all the passwords the same as the username
|Some points to consider|
|In prod envs we would use an existing schema, so we need to evaluate the available DDL scripts that I am sure exists.|
|I am installing without using installer defaulted profiles, this is because I want to show PMT`|
We need to explain all the profile types in the future
Some notes from IBM installation Guide for IBM Process Server
Some notes from install guide (PDF) to refer to when creating profiles. We cover the creation of a profile below.
Choosing a method for configuring a network deployment
You have three options for configuring a network deployment environment, if you are not using the configureNode command. You can use the Deployment Environment wizard, the Administrative Console, or the wsadmin command. They each configure a deployment environment after you have used the Profile Management Tool or the manageProfiles or zpmt.sh command to create server profiles.
If you select Deployment Environment wizard, the generated instructions include information about using the graphical interface tool to create the network deployment manager. If you select Administrative Console, the generated instructions include information about using the WebSphere Application Server Administrative console to create the deployment environment. If you select wsadmin commands (silent), the generated instructions include information about using command line interface to create the deployment environment, facilitating silent configuration.
These options are not available if you choose to perform a typical installation, in which case a profile is created automatically, or if you are installing a stand-alone environment, in which case you do not need a network deployment environment, or if you choose to use the configureNode command to create the profiles.
For now I am going to install the default template DMGR. Most of my articles for WAS ND cover on my blog and my WAS N Essentials course. Since this is a quick eval, I will use the defaults along with the default paths that get created and the default unique cell names etc.
Let’s choose a standard process server DMGR profile, then later we can create a node. To allow us to create single node cluster.
Click Next and choose Advanced profile creation. This gives us more options and visibility into settings.
Next, Next for SSL (more on that in the course) ie pros and cons of doing this now or later.
Next, Next (I never opt for auto restart)
Click Create to start the actual profile generation.
One create we can run the first steps console
Start the sever using the first steps console and then we can log into the administrative console.
After we will create a node.
admin console for my server is: https://192.168.1.82:9043/ibm/console/logon.jsp
Lets complete our WAS ND environment by adding a new node then we can deal with the deployment environment design.
Creating the Process Server deployment environment using a pattern
After determining the pattern on which to base your network deployment configuration, use the Deployment Environment Configuration wizard to create the IBM BPM Advanced Process Server deployment environment that is based on the pattern.
You should have planned the patterns and features that you want to configure
Using PMT tool we create another process server profile for the node.
I am summarizing you can use steps above for an idea of the PMT tool.
OK a little review on what we should have done
BM Business Process Manager V7.5 configurations
Different configurations of IBM® Business Process Manager correlate with typical entry points or stages in a company’s business process management program.

Single Cluster topology pattern
The Single Cluster topology pattern is an IBM-supplied topology pattern. In a Single Cluster topology pattern, all the functions of the deployment environment are combined into a single cluster.
A Single Cluster topology pattern is ideal for limited hardware. Because all the components are installed in the same cluster, fewer physical machines are required. However, because each server instance must run the supporting applications and your integration applications, you need more memory for the individual Java Virtual Machines (JVMs). In addition, one or more members of the cluster must also run the messaging engines required for asynchronous interactions. Thus, the Single Cluster topology pattern is typically used for proof of concept, development, and testing environments.
Combining all aspects of the IBM Business Process Manager environment into a single cluster has other implications aside from the increased memory requirements.
- Because asynchronous interactions (involving JMS and MQ/JMS bindings), human tasks, state machines, and long-running business processes can make extensive use of the messaging infrastructure, a single cluster environment is not ideal for applications with these components.
- Any messaging requirements must be kept to a minimum with this topology pattern
- Service Component Architecture (SCA) internal asynchronous invocations, the Java Message Service (JMS), and MQ messaging bindings do not support multiple messaging engines in the same cluster.
If necessary, choose one of the other topology patterns in which the messaging infrastructure is in a separate cluster from the application deployment target.
The Single Cluster topology pattern is suitable for scenarios that are focused on running applications and on synchronous invocations. This topology pattern is also not ideal if you intend to make extensive use of the Common Event Infrastructure (CEI). Generating events and CEI-related messaging traffic, places an additional burden on the cluster members.
From an administrative and scalability perspective, the Single Cluster topology pattern has advantages. A single cluster where each member runs all the IBM Business Process Manager components are simpler to administer. Instead of several server instances in multiple clusters, you have a single cluster with fewer members. If the needs of your environment grow, scaling the infrastructure is a simple matter of adding additional nodes and cluster members. Thus, the process of adding capability is simple, but all components are scaled at the same rate. For example, each additional cluster member adds CEI processing whether you need it or not. If the messaging engines spread across server members use policies, there could be some additional administrative effort in creating and maintaining the policies.
In a Single Cluster topology pattern, all deployment environment functions and components run on a single cluster:
- Service Component Architecture (SCA) application bus members
- SCA system bus members
- Business Process Choreographer bus members
- Business Process Choreographer components such as the Business Process Choreographer Explorer
- Business Process Choreographer container
- CEI bus members
- CEI server
- Business Rules manager
Application deployment target
You configure the application deployment target to support SCA applications and Business Process Choreographer components.
See the following graphical representation of the Single Cluster topology pattern.
The Process Center repository
The Process Center includes a repository for all processes, services, and other assets created in the IBM Business Process Manager authoring environments, Process Designer and Integration Designer.
The Process Center is a run time where Process Designer and Integration Designer share assets, in effect letting them develop business processes cooperatively in a highly interactive manner. These business processes can use monitoring points created with the Business Monitor development toolkit. The result is a business process that can be examined at runtime for effectiveness under real working conditions. Business Monitor provides a dashboard view with gauges and scorecards. You can add alerts and notifications that let you know from moment to moment how the business process is doing. Bottlenecks, inefficiencies, and errors in resource allocation in a running business process can be spotted and corrected resulting in improving the performance of your business processes.
In the diagram that follows, you see several related components that together let you build complex business processes.
The Process Center console provides the tools that you need to maintain the repository.
- From the Process Center console, you can create process applications and toolkits and grant other users access to those process applications and toolkits.
- In the authoring environments, you can create process models, services, and other assets within process applications.
- The Process Center includes a Process Center server and performance data warehouse, allowing users working in the authoring environments to run processes and store performance data for testing and playback purposes.
- From the Process Center console, administrators install process applications that are ready for testing or production on the process servers in those environments.
- From the Process Center console, administrators manage running instances of process applications in configured environments.
The Process Center console provides a convenient location in which to create and maintain high-level containers such as process applications and toolkits. Administrators who do not actively work in the Designer view can use the Process Center console to provide a framework in which BPM analysts and developers can build their processes and underlying implementations. Another primary task for administrators is managing access to the Process Center repository by setting up the appropriate authorization for users and groups.
Those users with appropriate authorization can perform some administrative tasks directly in Process Designer and Integration Designer. For example, a developer with write access to the process application who wants to capture the state of all project assets at a particular milestone can create a snapshot while working in the Designer view.
We will look into this after we have completed our WAS ND config.
|Start the node, if it is not started and let’s look in console. I should be started as part of the creation and federation|
|[root@localhost ~]# cd /opt/IBM/WebSphere/AppServer/profiles
[root@localhost profiles]# ls
[root@localhost profiles]# cd Node01/
[root@localhost Node01]# cd bin
[root@localhost bin]# ./startNode.sh
OK, we can now look into the BPM tools, Process Centre configurations in a WAS ND topology. Since we have WAS ND backing all of this we have flexibility in our cluster design. there are pros and cons for different cluster configs.
Any way we have completed part 1 of how to install IBM Process Server 8 on Linux to see how it all works
